ICD-10 Code E10.319 – Type 1 diabetes mellitus with unspecified diabetic retinopathy without macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.319 – Type 1 diabetes mellitus with unspecified diabetic retinopathy without macular edema
What it is
This code identifies type 1 diabetes complicated by diabetic retinopathy, but the retinopathy type is not further specified. The record also states there is no macular edema.
Clinical signs
Clinical features vary; refer to documentation. Retinopathy may be noted on eye examination with retinal microvascular changes, and the chart should state that macular edema is absent.
When to use this code
Use this code when the provider documents type 1 diabetes and diabetic retinopathy, but does not specify the retinopathy subtype. The diagnosis must also indicate no macular edema. If the eye note is incomplete, check documentation before coding.
Do not use for
Do not use this code if the record specifies proliferative, nonproliferative, or other named retinopathy types. Do not use it when macular edema is present or when retinopathy is not documented.
Coding tip
Look for both the diabetes type and the eye complication in the same provider documentation before assigning E10.319.
